Improving Safety and Operational Performance Through a TMSA Inspection Program
An independent TMSA gap analysis and inspection-readiness program identifying systemic weaknesses, implementing targeted corrective actions and improving safety performance, operational control and charterer confidence.
Case Study Overview
The Tanker Management and Self Assessment (TMSA) program provides a structured framework for tanker operators seeking continuous improvement in safety management, operational performance and technical excellence.
This case study describes how a medium-sized tanker operator used an independent gap analysis and structured inspection-preparation program to identify weaknesses, implement corrective actions and strengthen its overall TMSA performance.
Company Background
Fleet
12 oil and chemical tankers operating across international trading routes.
Operating Areas
Mediterranean, Middle East and Asia.
Personnel
Approximately 450 seafarers and 80 shore-based personnel.
Management Systems
ISM, ISO 9001, ISO 14001 and ISO 45001 certification framework.
Initial Situation
During the preceding two-year period, the company had identified several operational and management concerns requiring structured improvement.
- Increase in near-miss reports without sufficient trend analysis.
- Port State Control deficiencies.
- Inconsistent maintenance documentation.
- Crew fatigue concerns.
- Weak internal audit follow-up.
- Increased requests from major oil charterers for stronger evidence of TMSA implementation.
The company therefore initiated an independent technical gap-analysis program to assess its existing controls against applicable TMSA expectations and identify areas requiring corrective action.
Objectives of the TMSA Inspection Program
Compliance
Strengthen alignment with applicable OCIMF TMSA expectations and improve evidence of implementation.
Safety Performance
Improve vessel operational safety and reduce preventable deficiencies and incidents.
Risk Management
Strengthen hazard identification, risk assessment and corrective-action management.
Commercial Readiness
Improve charterer confidence and support future commercial opportunities with oil majors.

- Engine-room emergency drills.
- Cargo-handling simulations.
- Human-factor awareness workshops.
Internal Audits
- Monthly vessel audits.
- Shore management reviews.
- Increased senior management vessel visits.
Corrective Action Control
- Improved observation tracking.
- Defined responsibility for corrective actions.
- Management follow-up and verification.
Inspection Process
The external inspection was conducted over four days and included management-system review, vessel attendance, crew interviews and a formal closing meeting.
Day 1 – Documentation Review
The inspector reviewed the Safety Management System, training records, incident reports, maintenance logs, risk assessments and navigation procedures.
Documentation control was generally strong, although additional evidence of trend analysis for recurring near misses was required.
Day 2 – Vessel Inspection
One of the company's Aframax tankers was inspected, including the bridge, engine room, cargo control room, lifesaving appliances, firefighting equipment, permit-to-work systems and housekeeping arrangements.
Day 3 – Crew Interviews
Crew members were interviewed regarding safety culture, fatigue management, incident reporting, emergency response and stop-work authority.
Most crew members demonstrated good awareness of company procedures, while junior officers identified workload concerns during port operations.
Day 4 – Closing Meeting
Findings were reviewed with management and categorized into major non-conformities, minor non-conformities, observations and identified good practices.
Vessel Inspection Findings
Positive Findings
- Excellent bridge-team communication.
- Well-maintained engine room.
- High crew familiarity with emergency procedures.
Deficiencies Identified
- Expired calibration certificate for one gas detector.
- Incomplete enclosed-space entry checklist.
- Delayed maintenance for one ballast valve.
Inspection Outcome
| Finding Category | Number |
|---|---|
| Major Non-Conformities | 0 |
| Minor Non-Conformities | 3 |
| Observations | 5 |
| Best Practices | 4 |
Corrective Actions
Immediate Actions
- Renewed calibration certificates.
- Updated enclosed-space entry procedures.
- Completed overdue maintenance tasks.
Long-Term Improvements
- Revised work-rest scheduling.
- Additional officer recruitment.
- Digital fatigue monitoring system.
Safety Reporting
- Anonymous near-miss reporting.
- Monthly safety trend-analysis meetings.
- Safety recognition program.
Performance Monitoring
- KPI performance dashboard.
- Quarterly management review.
- Benchmarking against relevant industry performance.

TMSA Implementation FAQ
What is the main purpose of TMSA?
TMSA provides a structured framework for tanker operators to evaluate, measure and continuously improve safety-management and operational practices beyond basic compliance.
What weaknesses are commonly identified during TMSA reviews?
Common weaknesses may include ineffective KPI monitoring, limited incident trend analysis, inconsistent records, inadequate evidence of implementation and delays in closing corrective actions.
Why is crew engagement important during TMSA inspections?
Crew engagement helps demonstrate whether the company's safety culture is implemented in practice. Interviews and onboard interaction can reveal whether procedures, reporting systems and risk controls are understood and applied by personnel.
Why is fatigue management important?
Effective fatigue management supports safe operational performance by ensuring that work and rest arrangements, workload and personnel resources are appropriately managed.
Why is KPI monitoring important in TMSA?
Proactive KPI monitoring allows management to identify developing safety trends, measure performance, benchmark results and implement corrective action before recurring problems become more serious.
Can independent TMSA inspection-readiness support be provided?
Yes. PAMS Pacific Admiralty Maritime Services provides independent technical consultancy and inspection-readiness support covering gap analysis, technical review, documentation assessment, onboard readiness and practical corrective-action guidance within the agreed scope.
